Hello Canna-pet, My horse Roy has had a broken and dislocated leg and knee joint x 2years ago. He has recovered, but has been inflicted with Arthritis…. We started on Canna-pet a year and a half ago, and really notice a big difference in him! Without canna pet Roy gets stuck on the ground when he lays on his broken leg, my husband and I run out and flip him over on his good side and he gets up and runs off…on Canna Pet Max – he doesn’t have this problem nearly as much! Thank you! Julie
